摘要: An outbreak of Salmonella serotype stanley infections occurred in the United States and Finland 1995. The was investigated through case-control studies Arizona, Michigan, Finland; by isolate subtyping; tracing culturing implicated food. Alfalfa sprout consumption only exposure associated with S. Arizona (matched odds ratio [MOR] = 11.1; 95% confidence interval [CI], 1.4-513), Michigan (MOR 5.5; CI, 1.6-23), undefined; 4.9-infinity). US Finnish patient isolates were a unique strain distinct from not linked to outbreak. sprouts eaten patients 6 states traced seed shipped Dutch shipper. Thus, it concluded that alfalfa grown contaminated caused an international > or =242 =17 Finland. This illustrates new mechanism which contamination fresh produce can cause large, widely dispersed outbreaks.
